The foaming has taken place especially in the much infamous Varthur Lake. Because of the rains, toxic foam has spilled over to the nearby areas.

Authorities
had erected a mesh along the boundary of the lake to prevent the foam
from entering the streets but rain and heavy winds worsened the
situation with foam spilling over nearby roads & streets.

In
Focus

Social
media was abuzz with pictures & videos of the foam spilling over
the nearby areas and on the road. The civic bodies have constantly
failed to contain the situation despite much public & media
attention.

Till
now, only Bellandur and Varthur lakes were known for foaming and at
times even catching fire, but now, Huvinane and Subramanyapura Lakes
have also joined the list.

While
authorities are spending millions of rupees on preventing the froth
from spilling to nearby areas, much less efforts have been undertaken
to reduce the pollution in the lakes, which is the root cause of
foaming.

The
Bangalore Water Supply and Sewerage Board (BWSSB) in Bengaluru
had also installed a system of siphons. This system would help in
smooth movement of the lake water, thus reducing churning and thereby
reducing froth. But just one season's rain and this system failed
miserably.
